{"title":"2-Channel Marine Amplifiers","description":"\u003cp\u003eA \u003cstrong\u003e2-channel marine amplifier\u003c\/strong\u003e is the most versatile single component you can add to a boat audio system. Stereo operation powers a pair of cockpit or bow speakers cleanly — the difference over a head unit's built-in power is immediately obvious. Mono bridged operation consolidates both channels into a single high-power output to drive a subwoofer. One amplifier, two completely different system configurations.\u003c\/p\u003e\n\n\u003ch3\u003eStereo vs. Bridged: The Specs That Matter\u003c\/h3\u003e\n\u003cp\u003eEvery 2-channel marine amp will list two power specs:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStereo: X watts × 2 @ 4 ohm\u003c\/strong\u003e — this is the continuous power per channel in stereo mode, driving a standard 4-ohm speaker load.
